Application filed November 24, 1924. 1 Serial No. 752,013

The primary object of this invention is the I provision of a stop motion, mechanism for yarn winding machines, I

the size of the cop or ball'rof yarn'wound by means of which may be accurately regulated. I I

A further object of this invention is the provision of a stop motion mechanism for yarn winding machines, by means'of which the diameter of the yarn cop may be regulated, to prevent cuttingof the thread by friction, when the cop has reached a predetermined size. Y.

A further object of thisiinvention isthe provision of improved stop, motion mecha nism for regulating the size of yarn windings, bymeans of which windings of various sizes may be. obtained, and by means of which the cop may be accurately'regulated as to predetermined size, savingconsiderable quantities of yarn, which is apt to be destroyed by after thec'op' hasreached a predetermined size.

Referring regulating the size of the to the machine A, the same is preferably of the type illustrated and de scribed 1n Patent #1,018,920, granted Feb 1912,'t0 J.-O.l\-fcKean. In this ruary'. 27, machine, a cam 11 supported thereby.

a cam shaft 10 is'provided having the machine includes standards 12 upwardly of wh ch guide rods 13 are provided which slidably support a thread guide 14, which has a conventional lug-15 extending into the cam groove" of the cam '11. At the lower vided forv-rotatably receiving-pins; or shafts 18 and 19 therein, trated in Figure {l of the drawings.- The shafts 18 and 19 are'in axial alignment, and at the ends of the same which project inwardly from tliebeariiigs 17, the same sup portayoke socket 20 so that the yoke socket 20 maybe rocked with respect to the standards 12, in accordance with conventional *inding machine construction, as will be.

The'frame of 1 I 12, bearings are prosubstantially as is illus- I well understood by those skilled in the art to The yoke with an arm socket 2O upwardly is provided dle 21,.upon which a laterally extending spin 22; is'provided adapted to receive the cop shell or spool onto which the thread is to be wound. I

A spring 24 serv'esto hold the cop on the spindle 22 'yieldingly againsta loop driving roll .25, which :is of the conventional constrr ction.

I i-meinber. -26, lmown to the trade as the i v starting handle, is provided, which has depending spaced and aligning ears 27 bearing on the pin or s'haft extensions 18 and 19, and integral with said ears 27 is an upwardly plate-like arm 28, which normally at its upper end lies rearwardly of a shifter 29. The starting handle 26 also includes a forwardly extending arm 31 having a laterally projecting lug 32 thereon which is adapted to normally rest upon a latch 33 pivoted at 34c to a stationary bracket 35. On the latch 33 is provided a plate portion beneath which and forwardly of the pivot 34 is pivotally mounted one or more drops 36, each provided with an eye 8?, arms 88, and tail 39. The ends of the yarn that are being wound on the cop extend through the eyes 87 upwardly across a cross bar 40, and thence downwardly through a suitable thread guide to the cop on the spindle 22.

The operation of the winding mechanism thus far described. will be well understood by anyone skilled in the art to which this invention relates, and if any of the threads being wound should break, its drop 36 falls until stopped, by the tail 39 engaging the latch 33, which brings the arm 38 of the drop into the path of a vibrating arm 42 which is fixed to a shaft 4-3, as in conventional con struction. On its next upward stroke the arm 42 will strike the arm 38,. and thereby swing the latch 33 on its pivot 3 1 out from. beneath the lug 32, whereupon a spring at will actuate thestarting handle. structure 26 on the axis pr-videc by the shaft or pin extensions 18 and 19, so as to swing the shifter 29 upwardly and against the periphery of the cop being formed, and which action will move the cop supporting arm 21 forwardly, incident to the pivotal con nection of the yoke socket on the shaft extensions 1% audit), and move the cop out of engaging relation with the winding drum as can be readily understood. 1 y The stop motion above described will only automatically operate because of the breaking of a thread. It will not operate when the spool or cop has reached a predetermined size, so that it is a commonoccurrence for the cop. after reading a predetermined size, to have such great friction with the driving drum 25 that the threads on the cop are broken, and become tangled, causing cop is of a predetermined size or diameter,

l the a considerable loss of yarn. To this end, attachment B has been pro 'ided, which will cause the stop mechanism above dcrcribed to automatically operate when the and cause the cop support to move away rom yarn engaging relation with the same. The attachment B above mentioned includes the shaft or pin extension 18 above mentioned, and contemplates the provision of a set or clamping screw or member 50, whi h is av tln a wl t e inle s-diet 20, as is illustrated in Figure 4 of the drawings, to insure a movement of the pin 18 with the yoke socket, as the same is moved. To this end, it can readily be understood that the pin 18 bears in the bearing 17,

tioned, and the arm 52 also include; a laterally extendmg end portion 54, at right anglesito the body 58. A screw or clamp 55 is adjustably carried axially of the shaft or pin 18, for clamping against the body portion 53 of the trip arm 52,: whereby to clamp the trip arm 52 in a predetermined relation.

A post is also provided as a part of the attachment B, which has a screw threaded end 61 anda lock nut 62; the end of the post- 60 opposite the screw threaded end 61 being tapered or conical shaped, as at 64. This post 60 is adapted for screw threaded connection in a suitable screw threaded opening provided in the rear end of the plate portion of the latch arm 33 above described,

and so that the laterally extending hook portion 54 of the trip arm 52 may engage the same, as will now be described.

Referring to the operation of the improved attachment to automatically L-Yll) the top when it has reached a predetermined size, it can readily be understood from the foregoing descriptiomthatas the size of the cop increases the yoke socket 20 will be -n1oved forwardly, by reason of its pivotal movement with'th'e pinjor shaft extensions 18 and 19-as an axis. Due to the fact that the pin 18, is connected with the yoke socket 20 by reasonof the set screw 50. said pin 18 will likewise move with the yoke socket, and will swing the trip arm 52 therewith, so that as the cop increases in diameter, the end 54: of the arm 52 willmove towardthe poft 60. The end portion 54 of the arm 52 will first'engage the conical pointed head 61: of the post 60, and thereover will swing the latch 33 above mentioned, out of its holding relation with the lug 32 of the starting handle structure 26, releasing the same and permitting the spring 1 to actuate, in the manner above described. the starting handle, so that the brake 29 will move toengage th cop and move the same out of'winding relation with the drum By reason of the provision of the shaft or pin 18 carrying the trip arm 52, cops of various diameters may be run sip-Cs y moving downwardly porting device,

releasing the set screw 50 the shaft or pin extension 18 may be set as desired, so that the header end 54 of thetrip arm 52 will engage the post 60 at a predeterminedtime, when the cop has reached its maximum diameter desired. The tapered head of the post 60'is important, since thereby the trip v arm 52 is permitted to pass downwardly along the post when the winder tender pulls the spindle or arbor 22 forward to chang the cop for an empty tube. VVith this 'attachment it is impossible tostart the full tube and wind more yarn on the same, after the attachment has tripped the stop mecha nism as above described.

From the foregoing description of this invention it is apparent of stop motion mechanism has been provided, which will operate to automatically control the operation of winding apparatus, so that cops orballs of yarn ofpredetermined size, quantity, and diameter may be obtained. 7 q I Various changes in the'shape, size, and arrangement of parts may be made to the form of winding machine and attachment herein shown and described, without depart ing from the spirit ofthe invention or the scope of the claims.
